SPINDLE OF SPINNING, TWISTING, AN D LIKE'FRAMES.

use ofcentrifugal members for effecting bob-` bin drag on bobbins carried on dead spindles or on bobbins traversed up and down on ordinary spinning` spindles is known lin the trade. According to this invention centrifugalkmembersused yto drag bobbins on flyery spinning frames are carried around the spindle by' means of discs or stars coaxial with f the spindle vthe said discs or stars lhaving around their periphery receptacles tov re ceive the said centrifugal members those receptacles being open upwards so as to permit the insertion or removal of the centrifugal. members as required. This invention also* includes the application of centrifugal members to spindles or tubes carrying bobbins which spindles or tubes are driven at the same speed as the Viyers. By this` arrangey ment the cup or ring against which the cen,l Y trifugal members impinge is kept perfectlyV coaxial with the spindle or tube.

Fig. 16 is adetail of Fig. 15. In giving a first practical exampleof our invention as'applied to a worsted spinning frame we mount (Figs. 1, 2, and 3,) on a,l flyer spindle 1 `a bobbin 2-below it a disc 3 with open channels 31 onthe upper side of same; The said channels 31l radiate to the periphery of the disc. 'In the* channels 31 we layround'pinst preferably of wood,` one orl more. .A cup 5 is placed coaxially with the spindle 1 below'the disc 3 with it-sv sides embracing but clear of same.vk Against the inside ofthiscup 5 the round pins press by f centrifugal force'. The disc 3 has pins 32 upstanding whichuenter a slot in the bobbin and by means 0f Awhich it is dri-ven. On the cup 5 we mount a cap cover 6 fitting tightly on the outside ofthe cup 5"and coveringthe top of same but'with a hole to allow the disc 75 -3 to project upwardsand support the bobbin 2. Below the cup 5 we mount a lifting` rail 7 whichtraverses the'bobbin 2 up and down. 4In somecases we make the disc with the channels 82 (Figs. 1l and 5) for the cen- .3g

` trifugal members fl'cut right through" the disc 8. f

In a second illustration of our invention y i (Figs. 6 and 7) asl applied to a worsted spinning frame in which the bobbin is carried ona revolving tube mounted on a dead spindle on the lifting rail, we employ a lifting rail 7 traversed in a usual manner. On the lifting raily 7 we mount a dead spindle 11 and on the topv 111 of the dead spindle 11 we place 9o a tube 12. The tube has formed o n it at its l lower end a collar or `disc 3 and resting on -same is the spinningv bobbinr 2, which by means of a slot engaging with pins 32 on the disc drives the tube 12v and disc. The disc 3 has holesbored from its periphery vtowards the centre and in these we place centrifugal members L1.,y On the dead spindle 11y we mount below the tube 12 and disc'3 acup 5 the yupstanding edges which surround'but are clear of the disc 3. Against the inside of the cup 5 the centrifugal members 4 press and drag the spinning bobbins 2. In some cases we make the tube 16 (Figs. 8 and 9) with a disc 161 having the spaces for-the centrifugal member' ropen upwards. In a further case in the foregoing first and second arrangements instead of a cup around the disc we mount a ring 17 (Fig. 10) which can be lifted to allow ofk the insertion or removal of the centrifugal members into or from the disc. In still further cases we make the ring as described with a covering edge 18 (Fig. 11) to partially cover the disc.

In kgiving a third practical example of our invention as applied to a worsted spinning frame weemploy (Figs. 12, 13 and 14) a top flyer rail 21, a flyer 22 mounted in same with the legs hanging downwards (the flyer is driven by ordinary means), a lifting rail 7 supported and traversed in a usual manner, a spindle socket 24 with a spindle 25 mounted on the lifting rail 7. The spindle 25 and socket 24 are coaxial with the flyer 22. At the upper end 251 of the spindle 25 a wing 26 is jointed and folded to a horizontal position while working so as to engage with one of the flyer legs which drives the said spindles 25A. At the upper end of the spindle socket 24 we form a cup 241 and inl side of the cup 241 we place adisc 3 lan easy fit for the cup 241 and a Working fit on the spindle 25. On the upper side of the disc 3 two `pins 32 project and are driven by a spinning lbobbin`28 which we mount on the spindle 25. The bobbin 428 has holes to receive the pins 32 by which it drives the' disc 3. We form one or more holes 272 in the disc at right angles to the axis of the spindle and in these we put a wood pin orfpins4 with an easy fit. As the spindle 25 drives the bobbin 2 the pin orpins 4 fly outwards against the cup 241 and so retard the bobbin 2 and take up the yarn. The disc 3 being carried on a driven spindle 25 and in cup 241 absolutely central with the spindle 25 a very deli.- cate and regular drag is secured.

In giving a fourth practical example of our invention also as applied to a worsted spinning frame we employ (Figs. 15 and 16) a top rail 21, a flyer 22 mounted on same with legs 321 hanging downwards. The flyer 22 is .driven by 4means of a tape in ani ordinary manner. A lifting rail 7 is employed supported yand traversed in a usual manner and on it a dead spindle 34 coaxial with `the flyer 22. On the dead spindle 34 a -tube 35 is mounted `and supported on the upper end of same. At the lower end 351 0f the tube 3.5 we form a drag disc 36 having hdles 361bor'ed at right kangles to its axis a'ndradiating to the periphery of same. In

'theseho'le's l361 we place loose wood pins 37.

Around the periphery ofthe drag discwe mount a'r'i'ng or cup faneasy 'fit/for the drag disc 3. rIhe bobbin by means of pins 361 in the drag disc 3 drives same and by centrifugal force the wood pins 4 press outwards against the inside of the ring or cup 5 referred to, thereby imparting drag to the spinning bobbin 2 to make'it take up the thread.

Whether a tube is employed or not,` the bobbin is in each case mounted on the spindle for free rotation thereon.

We claim: I

In flyer spinning frames and the like, a spindle a bobbin mounted upon said spindle for free rotation thereon, and a holder attached to said bobbin and rotating therewith, in 1combination .with centrifugal members carried by said holder adapted to give a drag to said bobbin, the whole being adapted to permit lthe removal of said centrifugal members without removing .the 'holder from working position.
